Generally, a citizen of a foreign country who wishes to enter the United States must first obtain a visa, either a nonimmigrant visa for a temporary stay, or an immigrant visa for permanent residence. Visitor visas are nonimmigrant visas for persons who want to enter the United States temporarily for business (visa category B-1), for tourism (visa category B-2), or for a combination of both purposes (B-1/B-2).
There are several steps to apply for a visa. The order of these steps and how you complete them may vary by U.S. Embassy or Consulate. Please consult the instructions on the U.S. Embassy or Consulate website.
Online Nonimmigrant Visa Application, Form DS-160 – You must: 1) complete the online visa application and 2) print the application form confirmation page to bring to your interview. Photo – You will upload your photo while completing the online Form DS-160. Your photo must be in the format explained in the Photograph Requirements.
Interviews are generally required for visa applicants with certain limited exceptions below. Consular officers may require an interview of any visa applicant. You should schedule an appointment for your visa interview at the U.S. Embassy or Consulate in the country where you live. You may schedule your interview at another U.S. Embassy or Consulate, but be aware that it may be more difficult to qualify for a visa outside of the country where you live.
